Take advantage of as.matrix:

# keep the first column 
names <-  df.aree[,1]

# Transpose everything other than the first column
df.aree.T <- as.data.frame(as.matrix(t(df.aree[,-1])))

# Assign first column as the column names of the transposed dataframe
colnames(df.aree.T) <- names

If your value under test is a Double (not a primitive) and might be null (which is obviously not a number too), then you should use the following term:

(value==null || Double.isNaN(value))

Since isNaN() wants a primitive (rather than boxing any primitive double to a Double), passing a null value (which can't be unboxed to a Double) will result in an exception instead of the expected false.

If you code is intended for a different OS (like Mac OS X, Linux) you may use following:

#ifdef _WIN32
#define _CRT_SECURE_NO_DEPRECATE
#endif

document.getElementById('myframe1').contentWindow.document.getElementById('x')

Fiddle

contentWindow is supported by all browsers including the older versions of IE.

Note that if the iframe's src is from another domain, you won't be able to access its content due to the Same Origin Policy.

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:

1. Ctrl-G
2. A1:X50 Enter
3. Delete

Unless you have to do this very often, entering and then triggering the VBAcode is more effort.

And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S to select Goto Special and here select Formulas or Values.

You must have added new files in your commits which has not been pushed. Check the file and push that file again and the try pull / push it will work. This worked for me..

Adding further...

Every process has same virtual address space (If randomization of virtual address is stopped by using a flag in linux OS) (For more details Disable and re-enable address space layout randomization only for myself)

So if its one exe with no shared linking (Hypothetical scenario), then we can always give same virtual address to same asm instruction without any harm.

But when we want to link shared object to the exe, then we are not sure of the start address assigned to shared object as it will depend upon the order the shared objects were linked.That being said, asm instruction inside .so will always have different virtual address depending upon the process its linking to.

So one process can give start address to .so as 0x45678910 in its own virtual space and other process at the same time can give start address of 0x12131415 and if they do not use relative addressing, .so will not work at all.

So they always have to use the relative addressing mode and hence fpic option.

ART

According to the docs: http://web.archive.org/web/20170909233829/https://source.android.com/devices/tech/dalvik/configure an .odex file:

contains AOT compiled code for methods in the APK.

Furthermore, they appear to be regular shared libraries, since if you get any app, and check:

file /data/app/com.android.appname-*/oat/arm64/base.odex

it says:

base.odex: ELF shared object, 64-bit LSB arm64, stripped

and aarch64-linux-gnu-objdump -d base.odex seems to work and give some meaningful disassembly (but also some rubbish sections).

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

As referred to in the first answer, there are 32/64 bit scenarios which introduce build and runtime pitfalls for developers.

The solution is always to try to get right: What kind of software and OS you have installed.

For a small list of scenarios with the Oracle driver and the solution, you can visit this post.

Basically the same solution as provided by Rutger Kassies, but using a more pythonic syntax:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

data = np.arange(250, 260)

for ax, d in zip(axs.ravel(), data):
    ax.contourf(np.random.rand(10,10), 5, cmap=plt.cm.Oranges)
    ax.set_title(str(d))

Without purisms, I think that the best way to emulate scalar argument by reference in JavaScript is using object, like previous an answer tells.

However, I do a little bit different:

I've made the object assignment inside function call, so one can see the reference parameters near the function call. It increases the source readability.

In function declaration, I put the properties like a comment, for the very same reason: readability.

var r;

funcWithRefScalars(r = {amount:200, message:null} );
console.log(r.amount + " - " + r.message);


function funcWithRefScalars(o) {  // o(amount, message)
  o.amount  *= 1.2;
  o.message = "20% increase";
}

In the above example, null indicates clearly an output reference parameter.

The exit:

240 - 20% Increase

On the client-side, console.log should be replaced by alert.

? ? ?

Another method that can be even more readable:

var amount, message;

funcWithRefScalars(amount = [200], message = [null] );
console.log(amount[0] + " - " + message[0]);

function funcWithRefScalars(amount, message) {  // o(amount, message)
   amount[0]  *= 1.2;
   message[0] = "20% increase";
}

Here you don't even need to create new dummy names, like r above.

I'd like to propose a slight variation to getMethod() defined in uckelman's answer.

This version changes getMethod() by removing hard-coded values and simplifying usage a little. I recommend adding it to your PHPUnitUtil class as in the example below or to your PHPUnit_Framework_TestCase-extending class (or, I suppose, globally to your PHPUnitUtil file).

Since MyClass is being instantiated anyways and ReflectionClass can take a string or an object...

class PHPUnitUtil {
    /**
     * Get a private or protected method for testing/documentation purposes.
     * How to use for MyClass->foo():
     *      $cls = new MyClass();
     *      $foo = PHPUnitUtil::getPrivateMethod($cls, 'foo');
     *      $foo->invoke($cls, $...);
     * @param object $obj The instantiated instance of your class
     * @param string $name The name of your private/protected method
     * @return ReflectionMethod The method you asked for
     */
    public static function getPrivateMethod($obj, $name) {
      $class = new ReflectionClass($obj);
      $method = $class->getMethod($name);
      $method->setAccessible(true);
      return $method;
    }
    // ... some other functions
}

I also created an alias function getProtectedMethod() to be explicit what is expected, but that one's up to you.

Unfortunately, you can only have one app.config file per executable, so if you have DLL’s linked into your application, they cannot have their own app.config files.

Solution is: You don't need to put the App.config file in the Class Library's project.
You put the App.config file in the application that is referencing your class library's dll.

For example, let's say we have a class library named MyClasses.dll which uses the app.config file like so:

string connect = 
ConfigurationSettings.AppSettings["MyClasses.ConnectionString"];

Now, let's say we have an Windows Application named MyApp.exe which references MyClasses.dll. It would contain an App.config with an entry such as:

<appSettings>
    <add key="MyClasses.ConnectionString"
         value="Connection string body goes here" />
</appSettings>

OR

An xml file is best equivalent for app.config. Use xml serialize/deserialize as needed. You can call it what every you want. If your config is "static" and does not need to change, your could also add it to the project as an embedded resource.

Hope it gives some Idea

sample code:

<em><b>

$type=pathinfo($target,PATHINFO_EXTENSION);

  echo "Only mp4,3gp,avi file format are allowed to Upload";
  $errors=0;
 }
 //checking for Exsisting video Files
  if(file_exists($target)){
   echo "File Exist";
   $errors=0;
   }
  $filesize=$_FILES['video']['size'];
  if($filesize>250*2000000){
  echo 'You Can not Upload Large File(more than 500MB) by Default ini setting..<a     href="http://www.codenair.com/2018/03/how-to-upload-large-file-in-php.html">How to   upload large file in php</a>'; 
    $errors=0;
    }
   if($errors == 0){
   echo ' Your File Not Uploaded';
    }else{
 //Moving The video file to Desired Directory
  $uplaod_success=move_uploaded_file($_FILES['video']['tmp_name'],$target);
  if($uplaod_success){
  //Getting Selected video Information
    $name=$_FILES['video']['name'];
    $size=$_FILES['video']['size'];
    $result=mysqli_query($con,"INSERT INTO VIdeos           (name,size,type)VALUES('".$name."','".$size."','".$type."')");
    if($result==TRUE){
    echo "Your video '$name' Successfully Upload and Information Saved Our  Database";
    }
   }
  }
  }
 ?>

I tried all of the above solutions and none worked.

What I did was:

• Project clean
• Delete derived data
• Restart Xcode
• Re-enter the StoryboardID shown in previous answers (inside IB).

And then it worked. The shocking thing was that I had entered the Storyboar ID in interface builder and it got removed/deleted after opening Xcode again.

Hope this helps someone.

First get view (eg. by findViewById()) and then you can use getWidth() on the view itself.

No, not exactly. But it can inherit from a class and implement one or more interfaces.

Clear terminology is important when discussing concepts like this. One of the things that you'll see mark out Jon Skeet's writing, for example, both here and in print, is that he is always precise in the way he decribes things.

Another cause of this could be if you don't use the default variable name for the "id" which is actually: id.

You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.

To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)

egrep '(vmx|svm)' /proc/cpuinfo

To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.

This article explains exactly how to handle this: How do I... Serialize a hash table in C# when the application requires it?

I hope this is helpful

If you want the placeholder text to be red you need to target it specifically in CSS.

Write:

input::placeholder{
  color: #f00;
}

There are plenty available. Try using Modal windows of Jquery or DHTML would do good. Put the content in your div or Change your content in div dynamically and show it to the user. It won't be a popup but a modal window.
Jquery's Thickbox would clear your problem.

One more option

UPDATE x
SET x.CODE_DEST = x.New_CODE_DEST
FROM (
      SELECT CODE_DEST, ROW_NUMBER() OVER (ORDER BY [RS_NOM]) AS New_CODE_DEST
      FROM DESTINATAIRE_TEMP
      ) x

This solution worked for me using \copy.

psql -h <host> -U <user> -d <dbname> -c "\copy <table_name> FROM '<path to csvfile/file.csv>' with (format csv,header true, delimiter ',');"

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

If you don't want to clutter up your console with error messages, you can also run

git ls-files file_name

and then check the result. If git returns nothing, then the file is not tracked. If it's tracked, git will return the file path.

This comes in handy if you want to combine it in a script, for example PowerShell:

$gitResult = (git ls-files $_) | out-string
if ($gitResult.length -ne 0)
{
    ## do stuff with the tracked file
}

I was setting the url in Postman to be http:// but Apache was redirecting to https:// and somehow the POST variables were being dropped along the way.

After I changed it to https://, the POST variables worked properly.

Swift 3 and higher

let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
dateFormatter.timeStyle = .none
dateFormatter.locale = Locale.current
print(dateFormatter.string(from: date)) // Jan 2, 2001

This is also helpful when you want to localize your App. The Locale(identifier: ) uses the ISO 639-1 Code. See also the Apple Documentation

A portable approach that works equally well on Linux or Windows (where there is no /dev/null):

echo | gcc -dM -E -

For c++ you may use (replace c++11 with whatever version you use):

echo | gcc -x c++ -std=c++11 -dM -E -

It works by telling gcc to preprocess stdin (which is produced by echo) and print all preprocessor defines (search for -dletters). If you want to know what defines are added when you include a header file you can use -dD option which is similar to -dM but does not include predefined macros:

echo "#include <stdlib.h>" | gcc -x c++ -std=c++11 -dD -E -

Note, however, that empty input still produces lots of defines with -dD option.

We can use date -d option

1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12

date -d '20121212' +'%Y-%m-%d'

2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format

date -d '20121212 -7 days' +'%Y-%m-%d'

3) If we are getting date in some variable say dat

dat2=$(date -d "$dat -1 days" +'%Y%m%d')

FYI: A useful simulation tool - phpMyAdmin with Wampserver 3.0.6 - Preview SQL: I use 'Preview SQL' to see the SQL code that would be generated before you save the column with the change to ENUM. Preview SQL

Above you see that I have entered 'Ford','Toyota' into the ENUM but I am getting syntax ENUM(0) which is generating syntax error Query error 1064#

I then copy and paste and alter the SQL and run it through SQL with a positive result.

SQL changed

This is a quickfix that I use often and can also be used on existing ENUM values that need to be altered. Thought this might be useful.

Compiled some answers from here into re-usable ClaimsManager class with my additions.

Claims got persisted, user cookie updated, sign in refreshed.

Please note that ApplicationUser can be substituted with IdentityUser if you didn't customize former. Also in my case it needs to have slightly different logic in Development environment, so you might want to remove IWebHostEnvironment dependency.

The decision to use 1st January 1753 (1753-01-01) as the minimum date value for a datetime in SQL Server goes back to its Sybase origins.

The significance of the date itself though can be attributed to this man.

Philip Stanhope, 4th Earl of Chesterfield. Who steered the Calendar (New Style) Act 1750 through the British Parliament. This legislated for the adoption of the Gregorian calendar for Britain and its then colonies.

There were some missing days _{(internet archive link)} in the British calendar in 1752 when the adjustment was finally made from the Julian calendar. September 3, 1752 to September 13, 1752 were lost.

Kalen Delaney explained the choice this way

So, with 12 days lost, how can you compute dates? For example, how can you compute the number of days between October 12, 1492, and July 4, 1776? Do you include those missing 12 days? To avoid having to solve this problem, the original Sybase SQL Server developers decided not to allow dates before 1753. You can store earlier dates by using character fields, but you can't use any datetime functions with the earlier dates that you store in character fields.

The choice of 1753 does seem somewhat anglocentric however as many catholic countries in Europe had been using the calendar for 170 years before the British implementation (originally delayed due to opposition by the church). Conversely many countries did not reform their calendars until much later, 1918 in Russia. Indeed the October Revolution of 1917 started on 7 November under the Gregorian calendar.

Both datetime and the new datetime2 datatype mentioned in Joe's answer do not attempt to account for these local differences and simply use the Gregorian Calendar.

So with the greater range of datetime2

SELECT CONVERT(VARCHAR, DATEADD(DAY,-5,CAST('1752-09-13' AS DATETIME2)),100)

Returns

Sep  8 1752 12:00AM

One final point with the datetime2 data type is that it uses the proleptic Gregorian calendar projected backwards to well before it was actually invented so is of limited use in dealing with historic dates.

This contrasts with other Software implementations such as the Java Gregorian Calendar class which defaults to following the Julian Calendar for dates until October 4, 1582 then jumping to October 15, 1582 in the new Gregorian calendar. It correctly handles the Julian model of leap year before that date and the Gregorian model after that date. The cutover date may be changed by the caller by calling setGregorianChange().

A fairly entertaining article discussing some more peculiarities with the adoption of the calendar can be found here.

This is what you need!

Edit : See jme's answer for the best way with Python3.

Using pathlib, you have the following solution :

Let's say we want to check if son is a descendant of parent, and both are Path objects. We can get a list of the parts in the path with list(parent.parts). Then, we just check that the begining of the son is equal to the list of segments of the parent.

>>> lparent = list(parent.parts)
>>> lson = list(son.parts)
>>> if lson[:len(lparent)] == lparent:
>>> ... #parent is a parent of son :)

If you want to get the remaining part, you can just do

>>> ''.join(lson[len(lparent):])

It's a string, but you can of course use it as a constructor of an other Path object.

With some version-control plug-ins, it means that the local file has not yet been shared with the version-control repository. (In my install, this includes plug-ins for CVS and git, but not Perforce.)

You can sometimes see a list of these decorations in the plug-in's preferences under Team/X/Label Decorations, where X describes the version-control system.

For example, for CVS, the list looks like this:

These adornments are added to the object icons provided by Eclipse. For example, here's a table of icons for the Java development environment.

i think you are looking for groupBy function (using Lodash)

_personsList = [{"name":"Joe", "age":17}, 
                {"name":"Bob", "age":17}, 
                {"name":"Carl", "age": 35}];
_uniqAgeList = _.groupBy(_personsList,"age");
_uniqAges = Object.keys(_uniqAgeList);

produces result:

17,35

In .Net 1.1 and earlier, Application.Exit was not a wise choice and the MSDN docs specifically recommended against it because all message processing stopped immediately.

In later versions however, calling Application.Exit will result in Form.Close being called on all open forms in the application, thus giving you a chance to clean up after yourself, or even cancel the operation all together.

It's generally considered best-practice to only catch the errors you are interested in. In the case of shutil.rmtree it's probably OSError:

>>> shutil.rmtree("/fake/dir")
Traceback (most recent call last):
    [...]
OSError: [Errno 2] No such file or directory: '/fake/dir'

If you want to silently ignore that error, you would do:

try:
    shutil.rmtree(path)
except OSError:
    pass

Why? Say you (somehow) accidently pass the function an integer instead of a string, like:

shutil.rmtree(2)

It will give the error "TypeError: coercing to Unicode: need string or buffer, int found" - you probably don't want to ignore that, which can be difficult to debug.

If you definitely want to ignore all errors, catch Exception rather than a bare except: statement. Again, why?

Not specifying an exception catches every exception, including the SystemExit exception which for example sys.exit() uses:

>>> try:
...     sys.exit(1)
... except:
...     pass
... 
>>>

Compare this to the following, which correctly exits:

>>> try:
...     sys.exit(1)
... except Exception:
...     pass
... 
shell:~$ 

If you want to write ever better behaving code, the OSError exception can represent various errors, but in the example above we only want to ignore Errno 2, so we could be even more specific:

import errno

try:
    shutil.rmtree(path)
except OSError as e:
    if e.errno != errno.ENOENT:
        # ignore "No such file or directory", but re-raise other errors
        raise

Ended up doing this using csvfix:

csvfix map -fv '' -tv '0' /tmp/people.csv > /tmp/people_fixed.csv

In case you know for sure which columns were meant to be integer or float, you can specify just them:

csvfix map -f 1 -fv '' -tv '0' /tmp/people.csv > /tmp/people_fixed.csv

Without specifying the exact columns, one may experience an obvious side-effect, where a blank string will be turned into a string with a 0 character.

Heres the answer. Gotten from my reddit post... https://www.reddit.com/r/django/comments/6nq0bq/class_question_has_no_objects_member/

That's not an error, it's just a warning from VSC. Django adds that property dynamically to all model classes (it uses a lot of magic under the hood), so the IDE doesn't know about it by looking at the class declaration, so it warns you about a possible error (it's not). objects is in fact a Manager instance that helps with querying the DB. If you really want to get rid of that warning you could go to all your models and add objects = models.Manager() Now, VSC will see the objects declared and will not complain about it again.

With SQL server you can use this

SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS [MM/DD/YYYY];

with mysql server you can do the following

SELECT * FROM my_table WHERE YEAR(date_field) = '2006' AND MONTH(date_field) = '9' AND DAY(date_field) = '11'

SCAN doesn't require the client to load all the keys into memory like KEYS does. SCAN gives you an iterator you can use. I had a 1B records in my redis and I could never get enough memory to return all the keys at once.

Here is a python snippet to get all keys from the store matching a pattern and delete them:

import redis
r = redis.StrictRedis(host='localhost', port=6379, db=0)
for key in r.scan_iter("key_pattern*"):
    print key

I had the same problem and this is how i done it.

The GNU Coding Standard is a good reference for things like this. This section deals with the output of --help. In this case it is not very specific. You probably can't go wrong with printing a table showing the short and long options and a succinct description. Try to get the spacing between all arguments right for readability. You probably want to provide a man page (and possibly an info manual) for your tool to provide a more elaborate explanation.

Sometimes, such a question can be asked at an interview.

For example, when you write:

int a = 2;
long b = 3;
a = a + b;

there is no automatic typecasting. In C++ there will not be any error compiling the above code, but in Java you will get something like Incompatible type exception.

So to avoid it, you must write your code like this:

int a = 2;
long b = 3;
a += b;// No compilation error or any exception due to the auto typecasting

Start from m2e 0.13.0 (if not earlier than), you can convert a Java project to Maven project from the context menu. Here is how:

• Right click the Java project to pop up the context menu
• Select Configure > Convert to Maven Project

Here is the detailed steps with screen shots.

In my case, was the Docker that cause problems:

Note the difference with the added "?" character after ".php", especially when dealing with CodeIgniter:

RewriteRule ^(.*)$ index.php/$1 [L]

vs.

RewriteRule ^(.*)$ index.php?/$1 [L]

It depends on several other things.. if doesn't work, try the other option!

There's no direct equivalent, as it'd pause a webpage. However there is a setTimeout(), e.g.:

function doSomething() {
  thing = thing + 1;
  setTimeout(doSomething, 500);
}

Closure example (thanks Daniel):

function doSomething(val) {
  thing = thing + 1;
  setTimeout(function() { doSomething(val) }, 500);
}

The second argument is milliseconds before firing, you can use this for time events or waiting before performing an operation.

If maven works through proxy but not some of the plugins it is invoking, try setting JAVA_TOOL_OPTIONS as well with -Dhttp*.proxy* settings.

If you have already JAVA_OPTS just do

export JAVA_TOOL_OPTIONS=$JAVA_OPTS

The classic example, Dogs and cats are animals, animals have the method makeNoise. I can iterate through an array of animals calling makeNoise on them and expect that they would do there respective implementation.

The calling code does not have to know what specific animal they are.

Thats what I think of as polymorphism.

If your form is PHP based, it would work this way within your " <?php $data = array(" code:

    'onkeypress' => 'return /[a-z 0-9]/i.test(event.key)', 

Write it like this:

string[] files = Directory.GetFiles(@".\Archive", "*.zip");

. is for relative to the folder where you started your exe, and @ to allow \ in the name.

When using filters, you pass it as a second parameter. You can also add a third parameter to specify if you want to search recursively for the pattern.

In order to get the folder where your .exe actually resides, use:

var executingPath = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);

public static byte[] serialize(Object obj) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(out);
    os.writeObject(obj);
    return out.toByteArray();
}
public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {
    ByteArrayInputStream in = new ByteArrayInputStream(data);
    ObjectInputStream is = new ObjectInputStream(in);
    return is.readObject();
}

Create List of Single Item Repeated n Times in Python

Depending on your use-case, you want to use different techniques with different semantics.

Multiply a list for Immutable items

For immutable items, like None, bools, ints, floats, strings, tuples, or frozensets, you can do it like this:

[e] * 4

Note that this is usually only used with immutable items (strings, tuples, frozensets, ) in the list, because they all point to the same item in the same place in memory. I use this frequently when I have to build a table with a schema of all strings, so that I don't have to give a highly redundant one to one mapping.

schema = ['string'] * len(columns)

Multiply the list where we want the same item repeated

Multiplying a list gives us the same elements over and over. The need for this is rare:

[iter(iterable)] * 4

This is sometimes used to map an iterable into a list of lists:

>>> iterable = range(12)
>>> a_list = [iter(iterable)] * 4
>>> [[next(l) for l in a_list] for i in range(3)]
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11]]

We can see that a_list contains the same range iterator four times:

>>> a_list
[<range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>]

Mutable items

I've used Python for a long time now, and I have seen very few use-cases where I would do the above with mutable objects.

Instead, to get, say, a mutable empty list, set, or dict, you should do something like this:

list_of_lists = [[] for _ in columns]

The underscore is simply a throwaway variable name in this context.

If you only have the number, that would be:

list_of_lists = [[] for _ in range(4)]

The _ is not really special, but your coding environment style checker will probably complain if you don't intend to use the variable and use any other name.

Caveats for using the immutable method with mutable items:

Beware doing this with mutable objects, when you change one of them, they all change because they're all the same object:

foo = [[]] * 4
foo[0].append('x')

foo now returns:

[['x'], ['x'], ['x'], ['x']]

But with immutable objects, you can make it work because you change the reference, not the object:

>>> l = [0] * 4
>>> l[0] += 1
>>> l
[1, 0, 0, 0]

>>> l = [frozenset()] * 4
>>> l[0] |= set('abc')
>>> l
[frozenset(['a', 'c', 'b']), frozenset([]), frozenset([]), frozenset([])]

But again, mutable objects are no good for this, because in-place operations change the object, not the reference:

l = [set()] * 4
>>> l[0] |= set('abc')    
>>> l
[set(['a', 'c', 'b']), set(['a', 'c', 'b']), set(['a', 'c', 'b']), set(['a', 'c', 'b'])]

DELETE

The DELETE command is used to remove rows from a table. A WHERE clause can be used to only remove some rows. If no WHERE condition is specified, all rows will be removed. After performing a DELETE operation you need to COMMIT or ROLLBACK the transaction to make the change permanent or to undo it.

TRUNCATE

TRUNCATE removes all rows from a table. The operation cannot be rolled back ... As such, TRUCATE is faster and doesn't use as much undo space as a DELETE.

wait() works fine for me. The subprocesses p1, p2 and p3 are executed at the same. Therefore, all processes are done after 3 seconds.

import subprocess

processes = []

p1 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)
p2 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)
p3 = subprocess.Popen("sleep 3", stdout=subprocess.PIPE, shell=True)

processes.append(p1)
processes.append(p2)
processes.append(p3)

for p in processes:
    if p.wait() != 0:
        print("There was an error")

print("all processed finished")

Since you don't care, I chose the max ID for each number.

select tbl.* from tbl
inner join (
select max(id) as maxID, number from tbl group by number) maxID
on maxID.maxID = tbl.id

Query Explanation

 select 
    tbl.*  -- give me all the data from the base table (tbl) 
 from 
    tbl    
    inner join (  -- only return rows in tbl which match this subquery
        select 
            max(id) as maxID -- MAX (ie distinct) ID per GROUP BY below
        from 
            tbl 
        group by 
            NUMBER            -- how to group rows for the MAX aggregation
    ) maxID
        on maxID.maxID = tbl.id -- join condition ie only return rows in tbl 
                                -- whose ID is also a MAX ID for a given NUMBER

In Intellij13, you can use Editor configuration like below:

What worked for me was adding a div around the content. Originally i had this. Css applied to the td had no effect.

        <td>           
             @Html.DisplayFor(modelItem => item.Message)           
        </td>

Then I wrapped the content in a div and the css worked as expected

       <td>
            <div class="largeContent">
                @Html.DisplayFor(modelItem => item.Message)
            </div>
        </td>

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

If your array has static storage allocation, it is default initialized to zero. However, if the array has automatic storage allocation, then you can simply initialize all its elements to zero using an array initializer list which contains a zero.

// function scope
// this initializes all elements to 0
int arr[4] = {0};
// equivalent to
int arr[4] = {0, 0, 0, 0};

// file scope
int arr[4];
// equivalent to
int arr[4] = {0};

Please note that there is no standard way to initialize the elements of an array to a value other than zero using an initializer list which contains a single element (the value). You must explicitly initialize all elements of the array using the initializer list.

// initialize all elements to 4
int arr[4] = {4, 4, 4, 4};
// equivalent to
int arr[] = {4, 4, 4, 4};

When you start a thread you are executing a method of some chosen class. All attributes of that class are visible.

  Worker myWorker = new Worker( /* arguments */ );

  Thread myThread = new Thread(new ThreadStart(myWorker.doWork));

  myThread.Start();

Your thread is now in the doWork() method and can see any atrributes of myWorker, which may themselves be other objects. Now you just need to be careful to deal with the cases of having several threads all hitting those attributes at the same time.

You can use the ArrayList to put all the contents of the TextArea for exemple, and send as parameter by calling the save, as the writer just wrote string lines, then we use the "for" line by line to write our ArrayList in the end we will be content TextArea in txt file. if something does not make sense, I'm sorry is google translator and I who do not speak English.

Watch the Windows Notepad, it does not always jump lines, and shows all in one line, use Wordpad ok.

    SaveFile(NameFile, Text);
}

    path = "C:\\Users\\Paulo Brito\\Desktop\\" + name + ".txt";

    File file1 = new File(path);

    try {

        if (!file1.exists()) {

            file1.createNewFile();
        }


        File[] files = file1.listFiles();


        FileWriter fw = new FileWriter(file1, true);

        BufferedWriter bw = new BufferedWriter(fw);

        for (int i = 0; i < message.size(); i++) {

            bw.write(message.get(i));
            bw.newLine();
        }

        bw.close();
        fw.close();

        FileReader fr = new FileReader(file1);

        BufferedReader br = new BufferedReader(fr);

        fw = new FileWriter(file1, true);

        bw = new BufferedWriter(fw);

        while (br.ready()) {

            String line = br.readLine();

            System.out.println(line);

            bw.write(line);
            bw.newLine();

        }
        br.close();
        fr.close();

    } catch (IOException ex) {
        ex.printStackTrace();
        JOptionPane.showMessageDialog(null, "Error in" + ex);     
    }   
}

Your problem arises from the fact that $i has a blank value when your statement fails. Always quote your variables when performing comparisons if there is the slightest chance that one of them may be empty, e.g.:

if [ "$i" -ge 2 ] ; then
  ...
fi

This is because of how the shell treats variables. Assume the original example,

if [ $i -ge 2 ] ; then ...

The first thing that the shell does when executing that particular line of code is substitute the value of $i, just like your favorite editor's search & replace function would. So assume that $i is empty or, even more illustrative, assume that $i is a bunch of spaces! The shell will replace $i as follows:

if [     -ge 2 ] ; then ...

Now that variable substitutions are done, the shell proceeds with the comparison and.... fails because it cannot see anything intelligible to the left of -gt. However, quoting $i:

if [ "$i" -ge 2 ] ; then ...

becomes:

if [ "    " -ge 2 ] ; then ...

The shell now sees the double-quotes, and knows that you are actually comparing four blanks to 2 and will skip the if.

You also have the option of specifying a default value for $i if $i is blank, as follows:

if [ "${i:-0}" -ge 2 ] ; then ...

This will substitute the value 0 instead of $i is $i is undefined. I still maintain the quotes because, again, if $i is a bunch of blanks then it does not count as undefined, it will not be replaced with 0, and you will run into the problem once again.

Please read this when you have the time. The shell is treated like a black box by many, but it operates with very few and very simple rules - once you are aware of what those rules are (one of them being how variables work in the shell, as explained above) the shell will have no more secrets for you.

        $(function () {
            var val = '@Html.Raw(val)';
            var obj = $.parseJSON(val);
            console.log(0bj);
    });
    </script>

You can process your output synchronously or asynchronously.

1. Synchronous example

static void runCommand()
{
    Process process = new Process();
    process.StartInfo.FileName = "cmd.exe";
    process.StartInfo.Arguments = "/c DIR"; // Note the /c command (*)
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;
    process.Start();
    //* Read the output (or the error)
    string output = process.StandardOutput.ReadToEnd();
    Console.WriteLine(output);
    string err = process.StandardError.ReadToEnd();
    Console.WriteLine(err);
    process.WaitForExit();
}

Note that it's better to process both output and errors: they must be handled separately.

(*) For some commands (here StartInfo.Arguments) you must add the /c directive, otherwise the process freezes in the WaitForExit().

2. Asynchronous example

static void runCommand() 
{
    //* Create your Process
    Process process = new Process();
    process.StartInfo.FileName = "cmd.exe";
    process.StartInfo.Arguments = "/c DIR";
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;
    //* Set your output and error (asynchronous) handlers
    process.OutputDataReceived += new DataReceivedEventHandler(OutputHandler);
    process.ErrorDataReceived += new DataReceivedEventHandler(OutputHandler);
    //* Start process and handlers
    process.Start();
    process.BeginOutputReadLine();
    process.BeginErrorReadLine();
    process.WaitForExit();
}

static void OutputHandler(object sendingProcess, DataReceivedEventArgs outLine) 
{
    //* Do your stuff with the output (write to console/log/StringBuilder)
    Console.WriteLine(outLine.Data);
}

If you don't need to do complicate operations with the output, you can bypass the OutputHandler method, just adding the handlers directly inline:

//* Set your output and error (asynchronous) handlers
process.OutputDataReceived += (s, e) => Console.WriteLine(e.Data);
process.ErrorDataReceived += (s, e) => Console.WriteLine(e.Data);

Your question is kind of confusing; do you want to show only one row per user, or do you want to show a row per picture but suppress repeating values in the U.NAME field? I think you want the second; if not there are plenty of answers for the first.

Whether to display repeating values is display logic, which SQL wasn't really designed for. You can use a cursor in a loop to process the results row-by-row, but you will lose a lot of performance. If you have a "smart" frontend language like a .NET language or Java, whatever construction you put this data into can be cheaply manipulated to suppress repeating values before finally displaying it in the UI.

If you're using Microsoft SQL Server, and the transformation HAS to be done at the data layer, you may consider using a CTE (Computed Table Expression) to hold the initial query, then select values from each row of the CTE based on whether the columns in the previous row hold the same data. It'll be more performant than the cursor, but it'll be kinda messy either way. Observe:

USING CTE (Row, Name, PicID)
AS
(
    SELECT ROW_NUMBER() OVER (ORDER BY U.NAME, P.PIC_ID),
       U.NAME, P.PIC_ID
    FROM USERS U
        INNER JOIN POSTINGS P1
            ON U.EMAIL_ID = P1.EMAIL_ID
        INNER JOIN PICTURES P
            ON P1.PIC_ID = P.PIC_ID
    WHERE P.CAPTION LIKE '%car%'
    ORDER BY U.NAME, P.PIC_ID 
)
SELECT
    CASE WHEN current.Name == previous.Name THEN '' ELSE current.Name END,
    current.PicID
FROM CTE current
LEFT OUTER JOIN CTE previous
   ON current.Row = previous.Row + 1
ORDER BY current.Row

The above sample is TSQL-specific; it is not guaranteed to work in any other DBPL like PL/SQL, but I think most of the enterprise-level SQL engines have something similar.

Slightly off topic, but for those of you that want to modify the built-in colors of the Dark/Light themes you can use this little tool I wrote for Visual Studio 2012.

More info here:

Source Code

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname
... As before

It is possible to use the convert function here, but 36 characters are enough to hold the unique identifier value:

convert(nvarchar(36), requestID) as requestID

Consider the second script. If you import it in another one, the instructions, as at "global level", will be executed.

Just use window.open() function? The third parameter lets you specify window size.

Example

var strWindowFeatures = "location=yes,height=570,width=520,scrollbars=yes,status=yes";
var URL = "https://www.linkedin.com/cws/share?mini=true&url=" + location.href;
var win = window.open(URL, "_blank", strWindowFeatures);

Only these 3 tags seem to be required (og:title, twitter:description, rel="icon"):

<meta property="og:title" content="San Roque 2014 Pollos" />

<meta name="twitter:description" property="og:description" itemprop="description" content="Programa de fiestas" />

<link rel="icon" type="image/png" href="https://images.weserv.nl/?url=http://pollosweb.wesped.es/programa_pollos/play.png&w=192&height=192" sizes="192x192" />

Experimenting / playing

The easiest way to experiment for me was with CodeSandbox following these steps:

• Create a Vanilla app with https://codesandbox.io/s/
• Modify your meta tags accordingly in the index.html file
• Save the file (ctrl+s) which would fork the app and generate its own unique url
• Paste that url in WhatsApp to see the preview (you don't even need to send a message)
• Make changes to the meta tags
• Modify the url - add a single character at the end of the url. This discards the "previous cached preview"

Quotes required

Just be sure to ALWAYS have quotes and closing quotes because WhatsApp is sensitive to that. Your above example does not have a closing quote for your og:description.

You probably want to use Interactive Rebasing, which is described in detail in that link.

You can find other good resources if you search for "git rebase interactive".

Install ejs if it is not.

npm install ejs

Then after just paste below two lines in your main file. (like app.js, main.js)

app.set('view engine', 'html');

app.engine('html', require('ejs').renderFile);

If you're not using gradle (creating a project from an APK, for instance), this can be done through the Android Studio UI (as of version 3.3.2):

• Right-click the project root directory, pick Open Module Settings
• Hit the + Add Content Root button (center right)
• Add your path and hit OK

In my experience (with native code), as long as your .so's are built with debug symbols and from the same absolute paths, breakpoints added in source files will be automatically recognized.

Why not just have five separate images of a star (empty, quarter-full, half-full, three-quarter-full and full) then just inject the images into your DOM depending on the truncated or rouded value of rating multiplied by 4 (to get a whole numner for the quarters)?

For example, 4.8618164 multiplied by 4 and rounded is 19 which would be four and three quarter stars.

Alternatively (if you're lazy like me), just have one image selected from 21 (0 stars through 5 stars in one-quarter increments) and select the single image based on the aforementioned value. Then it's just one calculation followed by an image change in the DOM (rather than trying to change five different images).

Here is a solution in C#

    private static int heightOfTree(Node root)
    {
        if (root == null)
        {
            return 0;
        }

        int left = 1 + heightOfTree(root.left);
        int right = 1 + heightOfTree(root.right);

        return Math.Max(left, right);
    }

There is also OkHttp, which is an HTTP client that’s efficient by default:

• HTTP/2 support allows all requests to the same host to share a socket.
• Connection pooling reduces request latency (if HTTP/2 isn’t available).
• Transparent GZIP shrinks download sizes.
• Response caching avoids the network completely for repeat requests.

First create an instance of OkHttpClient:

OkHttpClient client = new OkHttpClient();

Then, prepare your GET request:

Request request = new Request.Builder()
      .url(url)
      .build();

finally, use OkHttpClient to send prepared Request:

Response response = client.newCall(request).execute();

For more details, you can consult the OkHttp's documentation

As already pointed out, nvcc depends on gcc 4.4. It is possible to configure nvcc to use the correct version of gcc without passing any compiler parameters by adding softlinks to the bin directory created with the nvcc install.

The default cuda binary directory (the installation default) is /usr/local/cuda/bin, adding a softlink to the correct version of gcc from this directory is sufficient:

sudo ln -s /usr/bin/gcc-4.4 /usr/local/cuda/bin/gcc

You are using ubuntu 12 (quite old one)

First, Open the /etc/mysql/mysql.conf.d/mysqld.cnf file (/etc/mysql/my.cnf in Ubuntu 14.04 and earlier versions

Under the [mysqld] Locate the Line, bind-address = 127.0.0.1 And change it to, bind-address = 0.0.0.0 or comment it

Then, Restart the Ubuntu MysQL Server systemctl restart mysql.service

Now Ubuntu Server will allow remote access to the MySQL Server, But still you need to configure MySQL users to allow access from any host.

User must be 'username'@'%' with all the required grants

To make sure that, MySQL server listens on all interfaces, run the netstat command as follows.

netstat -tulnp | grep mysql

Hope this works !

def update(value, nvalue):
    if not isinstance(value, dict) or not isinstance(nvalue, dict):
        return nvalue
    for k, v in nvalue.items():
        value.setdefault(k, dict())
        if isinstance(v, dict):
            v = update(value[k], v)
        value[k] = v
    return value

use dict or collections.Mapping

I always use the tag. It is a simple compile-time flag to catch little mistakes that I might make.

It will catch things like tostring() instead of toString()

The little things help in large projects.

Simple, standard library only. Gives timezone-aware datetime, unlike datetime.utcnow().

from datetime import datetime,timezone
now_utc = datetime.now(timezone.utc)

You may translate canvas by half-pixel distance.

ctx.translate(0.5, 0.5);

Initially the canvas positioning point between the physical pixels.

How about something like

git log --pretty=oneline master > 1
git log --pretty=oneline branch_A > 2

git rev-parse `diff 1 2 | tail -1 | cut -c 3-42`^

Its pretty simple. I saved the mysql community server in my D:\ drive. Hence this is how i did it.

Goto D:\mysql-5.7.18-winx64\bin and in the address bar type cmd and press enter, so command prompt will open. Now if you're using it for the first time type as mysql -u root -ppress enter. Then it will ask for password, again press enter. Thats it you are connected to the mysql server.

Before this make sure wamp or xampp any of the local server is running because i couldn't able to connect to mysql wihthout xampp running.

Happy Coding.

This should work, I think...

ResultSet results = st.executeQuery(sql);

if(results.next()) { //there is a row
 int id = results.getInt(1); //ID if its 1st column
 String str1 = results.getString(2);
 ...
}

You can also use the Number constructor/function (no need for a radix and usable for both integers and floats):

Number('09'); /=> 9
Number('09.0987'); /=> 9.0987

Alternatively like Andy E said in the comments you can use + for conversion

+'09'; /=> 9
+'09.0987'; /=> 9.0987

We've always used an

if(iserror(vlookup,"n/a",vlookup))

Excel 2007 introduced IfError which allows you to do the vlookup and add output in case of error, but that doesn't help you with 2003...

For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui files.

Initially I tried to use ui->setWindowTitle, but that doesn't exist. ui is not a QDialog or a QMainWindow.

The owner of the ui is the QDialog or QMainWindow, the .ui just describes how to lay it out. In that case, you would use:

this->setWindowTitle("New Title");

I hope this helps someone else.

I noticed a posting that say that it does not matter if you call a __stdcall from a __cdecl or visa versa. It does.

The reason: with __cdecl the arguments that are passed to the called functions are removed form the stack by the calling function, in __stdcall, the arguments are removed from the stack by the called function. If you call a __cdecl function with a __stdcall, the stack is not cleaned up at all, so eventually when the __cdecl uses a stacked based reference for arguments or return address will use the old data at the current stack pointer. If you call a __stdcall function from a __cdecl, the __stdcall function cleans up the arguments on the stack, and then the __cdecl function does it again, possibly removing the calling functions return information.

The Microsoft convention for C tries to circumvent this by mangling the names. A __cdecl function is prefixed with an underscore. A __stdcall function prefixes with an underscore and suffixed with an at sign “@” and the number of bytes to be removed. Eg __cdecl f(x) is linked as _f, __stdcall f(int x) is linked as _f@4 where sizeof(int) is 4 bytes)

If you manage to get past the linker, enjoy the debugging mess.

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

You can try this

 $('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});

The $('div.easy_editor') refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.

I got this error while I tried to write to a variable at the same time from different threads. Creating a private queue and making sure one thread at a time can write to that variabele at the same time. It was a dictionary in my case.

Random Number of Random Items from an Array

def random_items(array)
  array.sample(1 + rand(array.count))
end

Examples of possible results:

my_array = ["one", "two", "three"]
my_array.sample(1 + rand(my_array.count))

=> ["two", "three"]
=> ["one", "three", "two"]
=> ["two"]

I don't there there is any DataSource for the gridview
Though you have DataBind in your code as

gvdetails.DataBind(); 

For late-comers, it appears that groovy now support the :load file-path command which simply redirects input from the given file, so it is now trivial to include library scripts.

It works as input to the groovysh & as a line in a loaded file:
groovy:000> :load file1.groovy

file1.groovy can contain:
:load path/to/another/file invoke_fn_from_file();

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

The Python Magic library provides the functionality you need.

You can install the library with pip install python-magic and use it as follows:

>>> import magic

>>> magic.from_file('iceland.jpg')
'JPEG image data, JFIF standard 1.01'

>>> magic.from_file('iceland.jpg', mime=True)
'image/jpeg'

>>> magic.from_file('greenland.png')
'PNG image data, 600 x 1000, 8-bit colormap, non-interlaced'

>>> magic.from_file('greenland.png', mime=True)
'image/png'

The Python code in this case is calling to libmagic beneath the hood, which is the same library used by the *NIX file command. Thus, this does the same thing as the subprocess/shell-based answers, but without that overhead.

We are developing Versile Python (VPy), an implementation for python 2.6+ and 3.x of a new ORB/RPC framework. Functional AGPL dev releases for review and testing are available. VPy has native python capabilities similar to PyRo and RPyC via a general native objects layer (code example). The product is designed for platform-independent remote object interaction for implementations of Versile Platform.

Full disclosure: I work for the company developing VPy.

In Scripting languages like (JavaScript and old PHP versions) we use existing fundamental functions and method for performing our job. Lets take an example in JavaScript we can use ajax or web-sockets only if they are supported by browser or methods exist or them in browser. But in languages like C or C++ , Java we can write that feature from scratch even if any library for that feature is not available but we can't do so in JavaScript.

can you support web-sockets in Internet Explorer 8 or prior with the help of JavaScript But you can write a plugin in C or C++ or Java which may add a feature of web-socket to Internet Explorer 8.

Basically in Scripting languages we write a code in a sequence which execute existing methods in a sequence to complete our job. Entering numbers and formula in a digital calculator to do a operation is also a very example of scripting language.We should note that the compiler/run-time-environment of every scripting language is always written in programming language in which we can add more features and methods and can write new libraries.

PHP This is language which is somewhat b/w programming and scripting. We can add new methods by adding compiled extensions written in another High Level Language. We can't add high level features of networking or creating image processing libraries directly in PHP.

P.S. I am really sorry for revolving my answer around PHP JavaScript only but I use these two because I have a considerable experience in these two.

Given this piece of HTML code:

<a href='https://facebook.com/'>Facebook</a>
<a href='https://google.ca/'>Google</a>
<input type='text' placeholder='an input box'>

We can use this JavaScript:

function checkTabPress(e) {
    'use strict';
    var ele = document.activeElement;

    if (e.keyCode === 9 && ele.nodeName.toLowerCase() === 'a') {
        console.log(ele.href);
    }
}

document.addEventListener('keyup', function (e) {
    checkTabPress(e);
}, false);

I have bound an event listener to the document element for the keyUp event, which triggers a function to check if the Tab key was pressed (or technically, released).

The function checks the currently focused element and whether the NodeName is a. If so, it enters the if block and, in my case, writes the value of the href property to the JavaScript console.

Here's a jsFiddle

There are no classes in C, so it's impossible to to write dynamic_cast in that language. C structures don't have methods (as a result, they don't have virtual methods), so there is nothing "dynamic" in it.

Just remember, having "100% code-coverage" doesn't mean everything is tested completely - while it means every line of code is tested, it doesn't mean they are tested under every (common) situation..

I would use code-coverage to highlight bits of code that I should probably write tests for. For example, if whatever code-coverage tool shows myImportantFunction() isn't executed while running my current unit-tests, they should probably be improved.

Basically, 100% code-coverage doesn't mean your code is perfect. Use it as a guide to write more comprehensive (unit-)tests.

I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:

cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero

I experimented with values from 4K to 100M.

After letting dd to run for a while I killed it (Ctlr+C) and read the output:

36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s

As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.

My scores:

bs=   I/O rate
---------------
4K    13.5 MB/s
64K   18.3 MB/s
8M    19.1 MB/s <--- winner!
10M   19.0 MB/s
20M   18.6 MB/s
100M  18.6 MB/s   

Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda

In JavaScript functions are objects.

document.getElementById('foo').onclick = function(){
    prompt('Hello world');
}

If you don't want to add a new column, and you can guarantee that your current int column is unique, you could select all of the data out into a temporary table, drop the table and recreate with the IDENTITY column specified. Then using SET IDENTITY INSERT ON you can insert all of your data in the temporary table into the new table.

In dynamic languages, when the interpreter imports, it simply reads a file and evaluates it.

In C, external libraries are located by the linker at compile time to build the final object if the library is statically compiled, while for dynamic libraries a smaller version of the linker is called at runtime which remaps addresses and so makes code in the library available to the executable.

In Java, import is simply used by the compiler to let you name your classes by their unqualified name, let's say String instead of java.lang.String. You don't really need to import java.lang.* because the compiler does it by default. However this mechanism is just to save you some typing. Types in Java are fully qualified class names, so a String is really a java.lang.String object when the code is run. Packages are intended to prevent name clashes and allow two classes to have the same simple name, instead of relying on the old C convention of prefixing types like this. java_lang_String. This is called namespacing.

BTW, in Java there's the static import construct, which allows to further save typing if you use lots of constants from a certain class. In a compilation unit (a .java file) which declares

import static java.lang.Math.*;

you can use the constant PI in your code, instead of referencing it through Math.PI, and the method cos() instead of Math.cos(). So for example you can write

double r = cos(PI * theta);

Once you understand that classes are always referenced by their fully qualified name in the final bytecode, you must understand how the class code is actually loaded. This happens the first time an object of that class is created, or the first time a static member of the class is accessed. At this time, the ClassLoader tries to locate the class and instantiate it. If it can't find the class a NoClassDefFoundError is thrown (or a a ClassNotFoundException if the class is searched programmatically). To locate the class, the ClassLoader usually checks the paths listed in the $CLASSPATH environment variable.

To solve your problem, it seems you need an applet element like this

<applet
  codebase = "http://san.redenetimoveis.com"
  archive="test.jar, core.jar"
  code="com.colorfulwolf.webcamapplet.WebcamApplet"      
  width="550" height="550" >

BTW, you don't need to import the archives in the standard JRE.

To define a checked exception you create a subclass (or hierarchy of subclasses) of java.lang.Exception. For example:

public class FooException extends Exception {
  public FooException() { super(); }
  public FooException(String message) { super(message); }
  public FooException(String message, Throwable cause) { super(message, cause); }
  public FooException(Throwable cause) { super(cause); }
}

Methods that can potentially throw or propagate this exception must declare it:

public void calculate(int i) throws FooException, IOException;

... and code calling this method must either handle or propagate this exception (or both):

try {
  int i = 5;
  myObject.calculate(5);
} catch(FooException ex) {
  // Print error and terminate application.
  ex.printStackTrace();
  System.exit(1);
} catch(IOException ex) {
  // Rethrow as FooException.
  throw new FooException(ex);
}

You'll notice in the above example that IOException is caught and rethrown as FooException. This is a common technique used to encapsulate exceptions (typically when implementing an API).

Sometimes there will be situations where you don't want to force every method to declare your exception implementation in its throws clause. In this case you can create an unchecked exception. An unchecked exception is any exception that extends java.lang.RuntimeException (which itself is a subclass of java.lang.Exception):

public class FooRuntimeException extends RuntimeException {
  ...
}

Methods can throw or propagate FooRuntimeException exception without declaring it; e.g.

public void calculate(int i) {
  if (i < 0) {
    throw new FooRuntimeException("i < 0: " + i);
  }
}

Unchecked exceptions are typically used to denote a programmer error, for example passing an invalid argument to a method or attempting to breach an array index bounds.

The java.lang.Throwable class is the root of all errors and exceptions that can be thrown within Java. java.lang.Exception and java.lang.Error are both subclasses of Throwable. Anything that subclasses Throwable may be thrown or caught. However, it is typically bad practice to catch or throw Error as this is used to denote errors internal to the JVM that cannot usually be "handled" by the programmer (e.g. OutOfMemoryError). Likewise you should avoid catching Throwable, which could result in you catching Errors in addition to Exceptions.

shareInfo is Class:

public class ShareInfo
        {
            [JsonIgnore]
            public readonly DateTime Timestamp = DateTime.Now;
            [JsonProperty("sharename")]
            public string ShareName = null;
            [JsonProperty("readystate")]
            public string ReadyState = null;
            [JsonProperty("created")]
            [JsonConverter(typeof(Newtonsoft.Json.Converters.UnixDateTimeConverter))]
            public DateTime? CreatedUtc = null;
            [JsonProperty("title")]
            public string Title = null;
            [JsonProperty("getturl")]
            public string GettUrl = null;
            [JsonProperty("userid")]
            public string UserId = null;
            [JsonProperty("fullname")]
            public string Fullname = null;
            [JsonProperty("files")]

        }

// POST request.
            var gett = new WebClient { Encoding = Encoding.UTF8 };
            gett.Headers.Add("Content-Type", "application/json");
            byte[] request = Encoding.UTF8.GetBytes(jsonArgument.ToString());
            byte[] response = gett.UploadData(baseUri.Uri, request);

            // Response.
            var shareInfo = JsonConvert.DeserializeObject<ShareInfo>(Encoding.UTF8.GetString(response));

In Windows, if you have the shortcut in your taskbar, right-click the "Anaconda Prompt" icon, you'll see:

• Anaconda Prompt
• Unpin from taskbar (if pinned)
• Close window

Right-click on "Anaconda Prompt" again.

Click "Properties"

Add the path you want your anaconda prompt to open up into in the "Start In:" section.

Note - you can also do this by searching for "Anaconda Prompt" in the Start Menu. The directions above are specifically for the shortcut.

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

df[df.Letters=='C'].Letters.item()

This returns the first element in the Index/Series returned from that selection. In this case, the value is always the first element.

EDIT:

Or you can run a loc() and access the first element that way. This was shorter and is the way I have implemented it in the past.

• Pandas Series doc

git log --grep=<pattern>
            Limit the commits output to ones with log message that matches the
            specified pattern (regular expression).

That response is a string too, if you want to send the response prettified, for some awkward reason, you could use something like JSON.stringify(anObject, null, 3)

It's important that you set the Content-Type header to application/json, too.

var http = require('http');

var app = http.createServer(function(req,res){
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify({ a: 1 }));
});
app.listen(3000);

// > {"a":1}

Prettified:

var http = require('http');

var app = http.createServer(function(req,res){
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify({ a: 1 }, null, 3));
});
app.listen(3000);

// >  {
// >     "a": 1
// >  }

I'm not exactly sure why you want to terminate it with a newline, but you could just do JSON.stringify(...) + '\n' to achieve that.

Express

In express you can do this by changing the options instead.

'json replacer' JSON replacer callback, null by default

'json spaces' JSON response spaces for formatting, defaults to 2 in development, 0 in production

Not actually recommended to set to 40

app.set('json spaces', 40);

Then you could just respond with some json.

res.json({ a: 1 });

It'll use the 'json spaces' configuration to prettify it.

I have did it on windows machine. Detail mentioned below 1. From windows start menu open “Anaconda Prompt enter image description here 2. Find .jupyter folder file path . In command prompt just type enter image description here or enter image description here to find the .jupyter path

3. After find the .jupyter folder, check there has “jupyter_notebook_config” file or not. If it is not there then run below command enter image description here After run the command it will create "jupyter_notebook_config.py"

if do not have administrator permission then Some time you could not find .jupyter folder . Still you can open config file from any of the text editor

4. Open “jupyter_notebook_config.py” file from the the “.jypyter” folder.
5. After open the file need to update the directory is use for notebooks and kernel. There are so many line in config file so find “#c.NotebookApp.notebook_dir” and update the path enter image description here After: enter image description here Save the file
6. Now try to create or read some file from the location you set

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

This worked for me:

:%s/^[^a-zA-Z0-9]$\n//ig

It basically deletes all the lines that don't have a number or letter. Since all the items in my list had letters, it deleted all the blank lines.

In my case, I had created the map, but was missing the ReverseMap function. Adding it got rid of the error.

      private static void RegisterServices(ContainerBuilder bldr)
      {
         var config = new MapperConfiguration(cfg =>
         {
            cfg.AddProfile(new CampMappingProfile());
         });
         ...
       }


      public CampMappingProfile()
      {
         CreateMap<Talk, TalkModel>().ReverseMap();
         ...
      }

Only set the relevant / important CSS properties.

Example (only change the attributes which may cause your div to look completely different):

background: #FFF;
border: none;
color: #000;
display: block;
font: initial;
height: auto;
letter-spacing: normal;
line-height: normal;
margin: 0;
padding: 0;
text-transform: none;
visibility: visible;
width: auto;
word-spacing: normal;
z-index: auto;

Choose a very specific selector, such as div#donttouchme, <div id="donttouchme"></div>. Additionally, you can add `!important before every semicolon in the declaration. Your customers are deliberately trying to mess up your lay-out when this option fails.

In my macOS (10.13.3), I got it solved after reinstalling Node version manager.

A picture is worth a thousand words

Reminder:
Func<X, Y, R> is a function with two inputs of type X and Y, that returns a result of type R.

Enumerable.Aggregate has three overloads:

Overload 1:

A Aggregate<A>(IEnumerable<A> a, Func<A, A, A> f)

Example:

new[]{1,2,3,4}.Aggregate((x, y) => x + y);  // 10

This overload is simple, but it has the following limitations:

• the sequence must contain at least one element,
  otherwise the function will throw an InvalidOperationException.
• elements and result must be of the same type.

Overload 2:

B Aggregate<A, B>(IEnumerable<A> a, B bIn, Func<B, A, B> f)

Example:

var hayStack = new[] {"straw", "needle", "straw", "straw", "needle"};
var nNeedles = hayStack.Aggregate(0, (n, e) => e == "needle" ? n+1 : n);  // 2

This overload is more general:

• a seed value must be provided (bIn).
• the collection can be empty,
  in this case, the function will yield the seed value as result.
• elements and result can have different types.

Overload 3:

C Aggregate<A,B,C>(IEnumerable<A> a, B bIn, Func<B,A,B> f, Func<B,C> f2)

The third overload is not very useful IMO.
The same can be written more succinctly by using overload 2 followed by a function that transforms its result.

The illustrations are adapted from this excellent blogpost.

For Hibernate 5.2 and above, use CriteriaBuilder as follows

CriteriaBuilder builder = sessionFactory.getCriteriaBuilder();
CriteriaQuery<Cat> query = builder.createQuery(Cat.class);
Root<Cat> rootCat = query.from(Cat.class);
Join<Cat,Mother> joinMother = rootCat.join("mother");  // <-attribute name
Join<Mother,Kind> joinMotherKind = joinMother.join("kind");
query.select(rootCat).orderBy(builder.asc(joinMotherKind.get("value")));
Query<Cat> q = sessionFactory.getCurrentSession().createQuery(query);
List<Cat> cats = q.getResultList();

The suggestions don't work because they are for the standard MySQL driver, not for mysqli:

$this->db_link->error contains the error if one did occur

Or

mysqli_error($this->db_link)

will work.

At one point I had to parse and write XML that only consisted of elements without attributes so a 1:1 mapping from XML to dict was possible easily. This is what I came up with in case someone else also doesnt need attributes:

def xmltodict(element):
    if not isinstance(element, ElementTree.Element):
        raise ValueError("must pass xml.etree.ElementTree.Element object")

    def xmltodict_handler(parent_element):
        result = dict()
        for element in parent_element:
            if len(element):
                obj = xmltodict_handler(element)
            else:
                obj = element.text

            if result.get(element.tag):
                if hasattr(result[element.tag], "append"):
                    result[element.tag].append(obj)
                else:
                    result[element.tag] = [result[element.tag], obj]
            else:
                result[element.tag] = obj
        return result

    return {element.tag: xmltodict_handler(element)}


def dicttoxml(element):
    if not isinstance(element, dict):
        raise ValueError("must pass dict type")
    if len(element) != 1:
        raise ValueError("dict must have exactly one root key")

    def dicttoxml_handler(result, key, value):
        if isinstance(value, list):
            for e in value:
                dicttoxml_handler(result, key, e)
        elif isinstance(value, basestring):
            elem = ElementTree.Element(key)
            elem.text = value
            result.append(elem)
        elif isinstance(value, int) or isinstance(value, float):
            elem = ElementTree.Element(key)
            elem.text = str(value)
            result.append(elem)
        elif value is None:
            result.append(ElementTree.Element(key))
        else:
            res = ElementTree.Element(key)
            for k, v in value.items():
                dicttoxml_handler(res, k, v)
            result.append(res)

    result = ElementTree.Element(element.keys()[0])
    for key, value in element[element.keys()[0]].items():
        dicttoxml_handler(result, key, value)
    return result

def xmlfiletodict(filename):
    return xmltodict(ElementTree.parse(filename).getroot())

def dicttoxmlfile(element, filename):
    ElementTree.ElementTree(dicttoxml(element)).write(filename)

def xmlstringtodict(xmlstring):
    return xmltodict(ElementTree.fromstring(xmlstring).getroot())

def dicttoxmlstring(element):
    return ElementTree.tostring(dicttoxml(element))

SUMIF didn't worked for me, had to use SUMIFS.

=SUMIFS(TableAmount,TableMonth,"January")

TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.

Hope this can help someone!

At the cost of readability, I think this version is slightly faster as it doesn't force the while to reexamine the list, thus doing exactly the same work remove has to do anyway:

x = [1, 2, 3, 4, 2, 2, 3]
def remove_values_from_list(the_list, val):
    for i in range(the_list.count(val)):
        the_list.remove(val)

remove_values_from_list(x, 2)

print(x)

Use an interval to check

You can setup an interval to keep checking if the user has scrolled then do something accordingly.

Borrowing from the great John Resig in his article.

Example:

    let didScroll = false;

    window.onscroll = () => didScroll = true;

    setInterval(() => {
        if ( didScroll ) {
            didScroll = false;
            console.log('Someone scrolled me!')
        }
    }, 250);

See live example

mysql> INSERT INTO tb1 VALUES(1,1),(2,2),(3,3),(6,60),(7,70),(8,80);

mysql> INSERT INTO tb2 VALUES(1,1),(2,2),(3,3),(4,40),(5,50),(9,90);

DELETE records FROM one table :

mysql> DELETE tb1 FROM tb1,tb2 WHERE tb1.id= tb2.id;

DELETE RECORDS FROM both tables:

mysql> DELETE tb2,tb1 FROM tb2 JOIN tb1 USING(id);

Spring Boot, v2.3.0.RELEASE

Recommended (In application.properties):

logging.level.org.hibernate.SQL=DEBUG //logs all SQL DML statements
logging.level.org.hibernate.type=TRACE //logs all JDBC parameters 

parameters

Note:
The above will not give you a pretty-print though.
You can add it as a configuration:

properties.put("hibernate.format_sql", "true");

or as per below.

Works but NOT recommended

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

Reason: It's better to let the logging framework manage/optimize the output for you + it doesn't give you the prepared statement parameters.

For me, adding <script>window.print();</script> to the end of the page worked.

I didn't need the type="text/javascript" attribute, or even for the page to be wrapped in a <body> tag. However, all of my previous attempts to intuitively use the answers suggested here, of just writing window.onload=window.print or longer versions such as window.onload=()=>window.print(); did not work, and of course calling print on the newly created window does not wait for the contents to load.

First change the following parameters:

Tools -> Options -> Debugging -> Symbols -> Server -> Yes

Then press Ctrl+F5 and you will see amazing things.

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

One way is this:

select id, name, priority from table a
order by case when name='core' then -1 else priority end asc, priority asc

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

Technically yes. But only on certain instances. If for example you have the code page up and you hit git checkout, and you realize that you accidently checked out the wrong page or something. Go to the page and click undo. (for me, command + z), and it will go back to exactly where you were before you hit the good old git checkout.

This will not work if your page has been closed, and then you hit git checkout. It only works if the actual code page is open

If you intend on having multiple hosts/database connections, the ~/.pgpass file is the way to go.

Steps:

1. Create the file using vim ~/.pgpass or similar. Input your information in the following format: hostname:port:database:username:password Do not add string quotes around your field values. You can also use * as a wildcard for your port/database fields.
2. You must chmod 0600 ~/.pgpass in order for it to not be silently ignored by psql.
3. Create an alias in your bash profile that runs your psql command for you. For example:alias postygresy='psql --host hostname database_name -U username' The values should match those that you inputted to the ~/.pgpass file.
4. Source your bash profile with . ~/.bashrc or similar.
5. Type your alias from the command line.

Note that if you have an export PGPASSWORD='' variable set, it will take precedence over the file.

For number input or numeric keyboard you can use keyboardType: TextInputType.number

TextFormField(
  decoration: InputDecoration(labelText:'Amount'),
    controller: TextEditingController(
  ),
  validator: (value) {
    if (value.isEmpty) {
      return 'Enter Amount';
    }
  },
  keyboardType: TextInputType.number
)

I use Windows 10 Bash shell aka Linux Subsystem aka Ubuntu in Windows 10 as guided here

Set SSH up for Public Key Authentication, with no pasphrase on the Key. Loads of guides on the net. You won't need a password to login then. You can then limit connections for a key based on client hostname. Provides reasonable security and is great for automated logins.

For those who needs to stop all Threads running and re-run all of them when any one of them is stopped on an Exception:

@Override
public void onApplicationEvent(ContextRefreshedEvent event) {

     // could be any function
     getStockHistory();

}


public void getStockHistory() {

     // fill a list of symbol to be scrapped
     List<String> symbolListNYSE = stockEntityRepository
     .findByExchangeShortNameOnlySymbol(ContextRefreshExecutor.NYSE);


    storeSymbolList(symbolListNYSE, ContextRefreshExecutor.NYSE);

}


private void storeSymbolList(List<String> symbolList, String exchange) {

    int total = symbolList.size();

    // I create a list of Thread 
    List<Thread> listThread = new ArrayList<Thread>();

    // For each 1000 element of my scrapping ticker list I create a new Thread
    for (int i = 0; i <= total; i += 1000) {
        int l = i;

        Thread t1 = new Thread() {

            public void run() {

                // just a service that store in DB my ticker list
                storingService.getAndStoreStockPrice(symbolList, l, 1000, 
                MULTIPLE_STOCK_FILL, exchange);

            }

        };

    Thread.UncaughtExceptionHandler h = new Thread.UncaughtExceptionHandler() {
            public void uncaughtException(Thread thread, Throwable exception) {

                // stop thread if still running
                thread.interrupt();

                // go over every thread running and stop every one of them
                listThread.stream().forEach(tread -> tread.interrupt());

                // relaunch all the Thread via the main function
                getStockHistory();
            }
        };

        t1.start();
        t1.setUncaughtExceptionHandler(h);

        listThread.add(t1);

    }

}

To sum up :

You have a main function that create multiple thread, each of them has UncaughtExceptionHandler which is trigger by any Exception inside of a thread. You add every Thread to a List. If a UncaughtExceptionHandler is trigger it will loop through the List, stop every Thread and relaunch the main function recreation all the Thread.

function isUniform(array) {   
  for (var i=1; i< array.length; i++) {
    if (array[i] !== array[0]) { return false; }
  }

  for (var i=1; i< array.length; i++) {
    if (array[i] === array[0]) { return true; }
  }
}

• For the first loop; whenever it detects uneven, returns "false"
• The first loop runs, and if it returns false, we have "false"
• When it's not return false, it means there will be true, so we do the second loop. And of course we will have "true" from the second loop (because the first loop found it's NOT false)

You can use a powershell script (this works for users with folder redirection as well to not have their recycle bins take up server storage space)

$Shell = New-Object -ComObject Shell.Application
$RecBin = $Shell.Namespace(0xA)
$RecBin.Items() | %{Remove-Item $_.Path -Recurse -Confirm:$false}

The above script is taken from here.

If you have windows 10 and powershell 5 there is the Clear-RecycleBin commandlet.

To use Clear-RecycleBin inside PowerShell without confirmation, you can use Clear-RecycleBin -Force. Official documentation can be found here

This is CSS issues. I don't know why @Html.DropDownListFor in Bootstrap 4 doest work. Surely this is class design problem. Anyways the work arround is, if your Dropdown input box has CSS Padding: #px, # px; element then disable it. Hope this will work.

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

I just had to deal with this issue. @user3445140's answer helped me, but was much more than I needed to do.

1. Get your public SSH key with cat ~/.ssh/id_rsa.pub
2. Copy the key, including the "ssh-rsa" but excluding your computer name at the end
3. Go to https://github.com/settings/ssh
4. Add your SSH key

If you have updated your android studio, then go to FILE, Project Structure, Project, then check gradle version. Before that check your gradle version in C:\Program Files\Android\Android Studio\gradle and check the version if it matches then sync again else change the gradle version in android studio and sync again.

Not sure if this is more concise, but this function will also find and allow replacement of NAs (or any value you like) in selected columns of a data.table:

update.mat <- function(dt, cols, criteria) {
  require(data.table)
  x <- as.data.frame(which(criteria==TRUE, arr.ind = TRUE))
  y <- as.matrix(subset(x, x$col %in% which((names(dt) %in% cols), arr.ind = TRUE)))
  y
}

To apply it:

y[update.mat(y, c("a", "b"), is.na(y))] <- 0

The function creates a matrix of the selected columns and rows (cell coordinates) that meet the input criteria (in this case is.na == TRUE).

How about:

WHERE LEFT(job_no, 4) IN ('0711', '0712', ...)

Check the wiki: http://wiki.postgresql.org/wiki/Community_Guide_to_PostgreSQL_GUI_Tools

javascript:void(0); --> this executes void function and returns undefined. This could have issues with IE. javascript:; --> this does nothing. safest to create dead links. '#' --> this means pointing to same DOM, it will reload the page on click.

I then ran the .exe directly to perform the data import. And it worked!

You can also do (Get-Service -Name "what ever" - ComputerName RemoteHost).Status = "Stopped"

According to the select_list Oracle select documentation the AS is optional.

As a personal note I think it is easier to read with the AS

Not sure if this would be helpful. I am using a similar Amazon Linux AMI, which has tomcat7 living under /usr/share/tomcat7.

If tomcat is already running on your machine you can try:

ps -ef | grep tomcat

or

ps -ef | grep java

to check where it's running from.

For .NET People :

string instanceId = new StreamReader(
      HttpWebRequest.Create("http://169.254.169.254/latest/meta-data/instance-id")
      .GetResponse().GetResponseStream())
    .ReadToEnd();

There is special method:

a.unshift(value);

But if you want to prepend several elements to array it would be faster to use such a method:

var a = [1, 2, 3],
    b = [4, 5];

function prependArray(a, b) {
    var args = b;
    args.unshift(0);
    args.unshift(0);
    Array.prototype.splice.apply(a, args);
}

prependArray(a, b);
console.log(a); // -> [4, 5, 1, 2, 3]

Have you tried Hammerjs? It supports swipe gestures by using the velocity of the touch. http://eightmedia.github.com/hammer.js/

Use style="overflow:Scroll" in the label as in the below HTML. This will add the scroll bar in the label within the panel.

<asp:Label
    ID="txtAOI"
    runat="server"
    style="overflow:Scroll"
    CssClass="areatext"
    BackColor="White"
    BorderColor="Gray"
    BorderWidth="1"
    Width = "900" ></asp:Label>

Since both projects are under the same solution, there's a simpler way for the include files and linker as described in https://docs.microsoft.com/en-us/cpp/build/adding-references-in-visual-cpp-projects?view=vs-2019 :

1. The include can be written in a relative path (E.g. #include "../libProject/libHeader.h").
2. For the linker, right click on "References", Click on Add Reference, and choose the other project.

here is a sample of code using the CopyMemory function to do the job.

It is supposedly "much faster" (depending of the size and type of the array...).

i am not the author, but i tested it :

Sub RemoveArrayElement_Str(ByRef AryVar() As String, ByVal RemoveWhich As Long) 

'// The size of the array elements
'// In the case of string arrays, they are
'// simply 32 bit pointers to BSTR's.
Dim byteLen As Byte

'// String pointers are 4 bytes
byteLen = 4

'// The copymemory operation is not necessary unless
'// we are working with an array element that is not
'// at the end of the array
If RemoveWhich < UBound(AryVar) Then
    '// Copy the block of string pointers starting at
    ' the position after the
    '// removed item back one spot.
    CopyMemory ByVal VarPtr(AryVar(RemoveWhich)), ByVal _
        VarPtr(AryVar(RemoveWhich + 1)), (byteLen) * _
        (UBound(AryVar) - RemoveWhich)
End If

'// If we are removing the last array element
'// just deinitialize the array
'// otherwise chop the array down by one.
If UBound(AryVar) = LBound(AryVar) Then
    Erase AryVar
Else
    ReDim Preserve AryVar(LBound(AryVar) To UBound(AryVar) - 1)
End If
End Sub

<?php
ob_start();
var_dump($_POST['C']);
$result = ob_get_clean();
?>

if you want to capture the result in a variable

A solution with works with Python 2.X and Python 3.X makes use of the Python 2 and 3 compatibility library six:

from six.moves.urllib.request import urlopen
link = "http://www.somesite.com/details.pl?urn=2344"
response = urlopen(link)
content = response.read()
print(content)

add in manifiest file ,

  android:theme="@android:style/Theme.Translucent.NoTitleBar"

add following line into ur java file,

  this.requestWindowFeature(Window.FEATURE_NO_TITLE);

I find std::getline() is often the simplest. The optional delimiter parameter means it's not just for reading "lines":

#include <sstream>
#include <iostream>
#include <vector>

using namespace std;

int main() {
    vector<string> strings;
    istringstream f("denmark;sweden;india;us");
    string s;    
    while (getline(f, s, ';')) {
        cout << s << endl;
        strings.push_back(s);
    }
}

Running the command prompt or Powershell ISE as an administrator fixed this for me.

A linear search works by looking at each element in a list of data until it either finds the target or reaches the end. This results in O(n) performance on a given list. A binary search comes with the prerequisite that the data must be sorted. We can leverage this information to decrease the number of items we need to look at to find our target. We know that if we look at a random item in the data (let's say the middle item) and that item is greater than our target, then all items to the right of that item will also be greater than our target. This means that we only need to look at the left part of the data. Basically, each time we search for the target and miss, we can eliminate half of the remaining items. This gives us a nice O(log n) time complexity.

Just remember that sorting data, even with the most efficient algorithm, will always be slower than a linear search (the fastest sorting algorithms are O(n * log n)). So you should never sort data just to perform a single binary search later on. But if you will be performing many searches (say at least O(log n) searches), it may be worthwhile to sort the data so that you can perform binary searches. You might also consider other data structures such as a hash table in such situations.

Supposing you know when the list data has changed, you can manually tell the list to scroll to the bottom by setting the list selection to the last row. Something like:

private void scrollMyListViewToBottom() {
    myListView.post(new Runnable() {
        @Override
        public void run() {
            // Select the last row so it will scroll into view...
            myListView.setSelection(myListAdapter.getCount() - 1);
        }
    });
}

Another possibility is using the MySQL Workbench.

There is a JSON export option at the object browser context menu and at the result grid menu.

More information on MySQL documentation: Data export and import.

The following solution is different to the ones proposed so far, and works for me.

The rationale is that you select all matching children first, and then filter out the ones which are not direct children. A child is a direct child if it does not have a matching parent with the same selector.

function queryDirectChildren(parent, selector) {
    const nodes = parent.querySelectorAll(selector);
    const filteredNodes = [].slice.call(nodes).filter(n => 
        n.parentNode.closest(selector) === parent.closest(selector)
    );
    return filteredNodes;
}

HTH!

UPDATE: This is wrong answer, but it's still useful to understand why it's wrong. See comments.

How about unicode-escape?

>>> d = {1: "??? ????", 2: u"??? ????"}
>>> json_str = json.dumps(d).decode('unicode-escape').encode('utf8')
>>> print json_str
{"1": "??? ????", "2": "??? ????"}

This error raise because you not install postgres database in you project virtutal environment. you should run one of these command. from a terminal you can you command for sudo.

sudo apt-get install build-dep python-psycopg2

for pip (pip basically work for python)

pip install psycopg2

or

pip3 install psycopg2-binary

i'm pretty sure it will work for you.

There are a number of different icons and even splash screens that you can set for various devices. This answer goes through how to support them all.

Here are some snippets I have used with relevant links to where I gathered the information. See my blog for more information and more information about the ASP.NET MVC Boilerplate project template with all this built in right out of the box (Including sample image files).

Add the following mark-up to your html head. The commented out sections are entirely optional. While the uncommented sections are recommended to cover all icon usages. Don't be scared, most if it is comments to help you.

Total Overhead

If you take out the comments that's 3KB of extra HTML, if you don't support splash screens that's 1.5KB. If you are using GZIP compression on your HTML content, which everyone should be doing these days, that leaves you with about 634 Bytes of overhead per request to support all platforms or 446 Bytes without splash screens. I personally think its worth it to support IOS, Android and Windows devices but its your choice, I'm just giving the options!

Side Note About The Current Web Icon/Splash Screen/Settings Situation

This situation with vendor specific icons, splash screens and special tags to control the web browser or pinned icons is ridiculous. In a perfect world we would all use a favicon.svg file which could look good at any size and could be placed at the root of the page. Only FireFox supports this at the time of writing (See CanIUse.com).

However, icons are not the only setting these days, there are several other vendor specific settings (shown above) but a favicon.svg file would cover most use cases.

Update

Updated to include the new Android/Chrome version M39+ favicon/theming options. Interestingly, they have gone with a similar approach to Microsoft but are using a JSON file instead of XML.

First of all you don't use width=300px that's an attribute setting for the tag not CSS, use width: 300px; instead.

I would suggest applying the clearfix technique on the #outerdiv. Clearfix is a general solution to clear 2 floating divs so the parent div will expand to accommodate the 2 floating divs.

<div id='outerdiv' class='clearfix' style='width:600px; background-color: black;'>
    <div style='width:300px; float: left;'>
        <p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>
    </div>

    <div style='width:300px; float: left;'>
        <p>zzzzzzzzzzzzzzzzzzzzzzzzzzzzz</p>
    </div>
</div>

Here is an example of your situation and what Clearfix does to resolve it.

At the bottom of this answer is an example of GLSL code which allows to output the full float value as color, encoding IEEE 754 binary32. I use it like follows (this snippet gives out yy component of modelview matrix):

vec4 xAsColor=toColor(gl_ModelViewMatrix[1][1]);
if(bool(1)) // put 0 here to get lowest byte instead of three highest
    gl_FrontColor=vec4(xAsColor.rgb,1);
else
    gl_FrontColor=vec4(xAsColor.a,0,0,1);

After you get this on screen, you can just take any color picker, format the color as HTML (appending 00 to the rgb value if you don't need higher precision, and doing a second pass to get the lower byte if you do), and you get the hexadecimal representation of the float as IEEE 754 binary32.

Here's the actual implementation of toColor():

This will work for sure!

You can use this Javascript :

function getParameterByName(name) {
    var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}

OR

You can also use the plugin jQuery-URL-Parser allows to retrieve all parts of URL, including anchor, host, etc.

Usage is very simple and cool:

$.url().param("itemID")

The way I managed to get mine to work was by using CompoundButtonCompat.setButtonTintList(button, colour).

To my understanding this works regardless of android version.

1. The class Date/Timestamp represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.

2. Date/Timestamp doesn't know about the given time is on which timezone.

3. If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.

4. If you try to print a Date/Timestamp object using toString(), it will convert and print the time with the default timezone of your machine.

5. So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)

6. To conclude Date.getTime() will give UTC time, but toString() is on locale specific timezone, not UTC.

Now how will I create/change time on specified timezone?

The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.

   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
   dateFormatLocal.setTimeZone(timeZone);
   java.util.Date parsedDate = dateFormatLocal.parse(date);

Use dateFormat.format for taking input Date (which is always UTC), timezone and return date as String.

How to store UTC/GMT time in DB:

If you print the parsedDate object, the time will be in default timezone. But you can store the UTC time in DB like below.

        Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
        if (tsSchedStartTime != null) {
            stmt.setTimestamp(11, tsSchedStartTime, calGMT );
        } else {
            stmt.setNull(11, java.sql.Types.DATE);
        }

Updated (11/2017) to take into consideration some comments.

Easy example:

wchar_t buf[256];
FormatMessageW(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
               NULL, GetLastError(), MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), 
               buf, (sizeof(buf) / sizeof(wchar_t)), NULL);
